<p>Samsonite, swissgear, oakley, are all really good bags that my brother has used. He carries the whole load with him, and his laptop could be secured inside the bags, as they have a lot of straps. There is also really good padding for the shoulders, and airflow, and back support.
The other one that he uses is the clive bags, which I have to say are amazing! Some models even allow a skateboard strap, which is really useful.</p>
